    Description

    The LSG-1900B Near Field Moving Detector Goniophotometer is a Type C automated goniophotometric instrument engineered for precise luminous intensity distribution measurement in accordance with international photometric standards. This system incorporates a temperature-stabilized detector to ensure measurement stability and repeatability across extended testing periods.

    Primary Applications: Industrial laboratory photometric characterization of compact luminaires including downlights, bulb lights, LED modules, and other small-scale lighting products requiring detailed spatial light distribution analysis.

    Measurement Capabilities: The LSG-1900B performs comprehensive photometric analysis including:
    • Luminous Intensity Distribution Curves
    • Zonal Luminous Flux Calculations
    • Luminaire Efficacy Determination
    • Luminance Distribution Mapping
    • Coefficient of Utilization Analysis
    • Glare Evaluation via Luminance Limitation Curves
    • Maximum Distance-to-Height Ratio Assessment
    • Equal Illuminance Diagram Generation
    • Luminaire-to-Lighting Area Correlation Curves
    • Isocandela Diagram Production
    • Effective Luminescence Angle Measurement

    Technical Specifications:
    • Standards Compliance: Meets requirements of CIE S 025, IEC 60598-1, IES LM-79, and GB/T 9468
    • Measurement Modes: Supports both C-γ and B-β coordinate system measurements
    • Burn Position Stability: Maintains fixed burning point position throughout rotation cycles
    • Rotation Capability: Luminaire rotates through γ-axis ±180° (0-360°) and C-axis ±180° (0-360°)
    • Maximum Test Sample: Φ300mm diameter × 550mm height; 20kg maximum weight; 10A current capacity
    • Measurement Geometry: 1250mm fixed distance between luminaire and detector
    • Photometric Range: Light intensity measurement from 0.015cd to 107cd
    • Angular Precision: 0.2° accuracy with 0.01° resolution
    • Photometric Accuracy: Class A per international standards
    • Software Compatibility: English interface compatible with Windows 7, 8, 10, and 11 operating systems
    • Data Export Formats: Generates CIE, IES, LDT, and other standard photometric data files compatible with illumination design software including Dialux
